Extreme wide-angle eyepiece with best possible correction field geometry and colour errors.
The massive eyepiece body has a high-quality anodised finish, the lens system is fully multi-coated for high light transmission and the lens edges are effectively blackened.
Other special features:
- Simple conversion from 2” to 1.25” by removing the threaded sleeve (excluding the 20mm eyepiece)
- Waterproof version
- Filter thread for 1.25” and 2” (excluding the 20mm eyepiece)
- Conical upper eyepiece end for use on binocular attachments
- Removable eye cups with M44.5 x 0.75 external thread for cameras underneath
The eyepiece is a perfect companion for Deep Sky observations even at high magnifications: the object remains fully visible, even if you want to observe a larger nebula or star cluster.
